Beneficiation test of fine fluorite by micro bubble countercurrent contact flotation column
Fluorite, also known as fluorspar, is mainly composed of CaF2 with a relative density of 3.0 ‐ 3.2. Fluorite is a common mineral, which is widely distributed. According to the statistics of the United States Geological Survey in 2015, the fluorite mineral resources identified globally are about 500 million tons, and the reserves identified are about 250 million tons. China's fluorite reserves rank the third in the world, second only to South Africa and Mexico. As a strategic non-metallic raw material, fluorite is widely used in chemical industry, building materials, ceramics, metallurgy and other fields. With the gradual shortage of high-quality fluorite resources, it is of great significance to carry out beneficiation test research on fine fluorite with low raw ore grade and complex embedded particle size.

Four types of fluorite ores and their beneficiation methods
Fluorite, also known as fluorite, is mainly composed of CaF2, with a relative density of 3.0 ‐ 3.2, a Mohs hardness of 4, a brittle property, and a melting point of 1270-1350 ℃. Fluorite is a common mineral, which is widely distributed. According to the statistics of the United States Geological Survey in 2015, the fluorite mineral resources identified globally are about 500 million tons, and the reserves identified are about 250 million tons. China's fluorite reserves rank the third in the world, second only to South Africa and Mexico.

Current Situation and Prospect of Tungsten Beneficiation Research in China
Tungsten is an important strategic metal, which is widely used in modern technology in pure metal state and alloy state. The pure metal of tungsten is silver white, with high hardness, strength and wear resistance. Alloy steel, tungsten carbide based cemented carbide, wear-resistant alloy and strong thermal alloy are the main alloy states of tungsten. Tungsten is widely used in electrical, metal rolling, mechanical processing, geotechnical engineering, aerospace, military and other fields. At present, tungsten is mainly used to manufacture cemented carbide, filament, high-speed cutting alloy steel and heat-resistant special steel, rocket thruster nozzle and firearms.
